Nostradamus Quatrain century 2: 43.
During the appearance of the bearded star, the three great princes will be made enemies. The tremulous peace on earth will be struck from the skies; the Po, the winding Tiber, a serpent on the shore
Line 1: Comets were called bearded stars. Line 2: Three great nations – only 3 possible major powers are USA, China and North Korea. So they are possible candidates Line 3: A strike from the sky shatters peace (asteroid in comets tail) Line 4: Earthquakes in Italy/ France resulting from impact causing flooding.
